' STRAINER Filed Dec: 6, 1928 avwemtoz Patented May 13, 1930 lanai? PATENT OFFICE JOHN SALVATORE, OF EAST ORANGE, NEW JERSEY STRAINER Application filed December 6, 1928. Serial No. 324,088.

The main object of this invention is to provide a strainer suitable for bath tubs, basins or wash tubs, and is fitted in the drain pipe in such manner that it may be readily removed so that the refuse deposited upon the strainer may be readily removed.

Another object of this invention is to provide a strainer so constructed that it may be fitted to the present type of drain pipe in a manner which will allow the removal of the entire device or the strainer by itself so that the refuse deposited upon the strainer may be cleaned therefrom. I

The above and other objects will become apparent in the description below, in which characters of reference refer to like-named parts in the drawing.

Referring briefly to the drawing, Figure 1 is a perspective View ofthe strainer disc.

Figure 2 is a longitudinal sectional elevational View of a drain pipe showing the strainer mounted therein.

Referring in detail to the drawing, the present-day type of drain pipes, is indicated by the numeral 11, having a cross 13 anchored at one position in the drain pipe. The device comprises a tubular cage 14 which is open at both ends and is provided with opposing slots 15 which communicate with one end of the cage and do not extend the entire length of the latter. This cage seats upon the surface of the cross 13 and may be readily removed when desired. The strainer, consisting of a disc 16 of the same conformation as the interior of the cage, is used with this device. This strainer is provided with a plurality of perforationsl'? which are of suitable area to permit the passage of liquid therethrough and, at the same'time, stop 40 the passage of particles which would tend to impede the flow of water through the drain pipe. The disc has lips 18 extending therefrom at various positions around the edge thereof. These lips 18 are adapted to be inserted into the slots 15 of the cage. An

upright stem 19 rises from the axis of the disc 16 and has a flattened upper end, as 1ndicated by the numeral 20, to provide grip means for removing the strainer from the drain pipe. The cage, as stated, seats upon the cross 13 of the drain pipe and supports the entire device. The upright stem of the strainer rises to a position level with the surface of the drain pipe flange 22 and no higher. This permits the usual type of hollow stopper 23 to be inserted at the upper open'end of the drain pipe to close the same when it is desired to.retain the water or liquid in the basin, wash tub or bath tub.

The primary service which the strainer renders in the apparatus is to prevent the reception of refuse particles, such as hair, or the refuse in washing, from entering the drain pipe and clogging the same. The water may readily seep through the-perforations 17 of the strainer disc and pass directly into the drain pine. 7

It is to be noted that certain changes in form and construction may be made without departing from the spirit and scope of the invention.

I claim: 7

1. In a drain pipe having a cross fixture therein, a perforated disc, a stem on said disc, lips projecting from said disc, and means removable from said drain pipe for supporting said disc above said cross.

2. In a drain pipe having a cross fixture removable from said drain pipe for supporting said disc above said cross, a cage adapted to seat on said cross, and means in said cage receiving the lips of said perforated disc for supporting the latter.

3. In a drain pipe having a cross fixture therein, a perforated disc, a stem on said disc, lips projecting from said disc, and means removable from said drain pipe for supporting said disc above said cross, a cage adapted to seat on said cross, said cage having slots therein, the slots receiving the lips of said perforated disc to guide the same to supporting position at the lower closed ends of said slots.

In testimony whereof I affix my signature.
